西北城市河道整治模式优选研究

Optimization of training patterns of urban river in China's northwestern cities

通过分析西北城市河道特点,对西北城市河道常用整治模式进行了分类,建立了包括建设运行、生态景观、社会经济和防洪安全4个方面8个类别共26个指标的西北城市河道整治模式优选指标体系,并建立AHP-FCM模型对西北城市河道整治模式进行比选分析.应用AHP-FCM模型对内蒙古乌海市摩尔沟河道整治模式进行优选,结果表明,该模型是合理的、可行的.

The characteristics of urban rivers in China＇s northwestern cities were analyzed,and the training patterns of the urban rivers were defined and classified.An assessment index system for the optimization of urban rivers in China＇s northwestern cities was established,including 4 aspects of construction and operation,ecological landscape,social economy and flood control safety with 8 categories and 24 indices.A model based on the fuzzy consistent matrix and the analytic hierarchy process（AHP-FCM） was proposed to compare the training patterns of urban rivers.Through a training project of Mo＇er River in Wuhai City of Inner Mongolia,the optimization results were calculated according to the characteristics of its upper,middle and lower reaches by use of the proposed AHP-FCM model,that is,double-channel,three-channel and single-channel patterns for the upper,middle and lower reaches,respectively.Rationality analysis of the results demonstrates that the proposed model is feasible and practical.
